Solar cell assembly and solar cell module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solar panel clamping assemblies are prone to reduced clamp force due to aging from ultraviolet rays, water vapor, and corrosion, and have poor resistance to air and snow pressure, leading to potential deformation and dislodgment of solar panels, especially requiring high installation accuracy which can be challenging, especially when installing near the ground.
Innovation Solution
A solar cell assembly with an installation member featuring a supporting portion on the backside of the solar panel and a connecting portion extending parallel to the panel, allowing for adhesion and bolt fixation from the front, enhancing load-bearing capacity and reducing installation accuracy requirements, while facilitating connection to various support beams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional clamping assembly with rubber pad is used to fix the solar panel, then the solar panel can be installed and fixed, but the rubber pad ages under ultraviolet rays, water vapor and corrosion gases, reducing clamp force and causing the solar panel to drop off
Solution Approach 1:
The patent removes the rubber pad from the clamping assembly, extracting the aging component that caused reliability degradation. The aluminum clamp directly contacts the solar panel frame without relying on rubber pads that deteriorate under environmental exposure.
Solution Approach 2:
The patent eliminates the need for replaceable rubber pads by using a direct metal-to-metal contact system. The aluminum clamp provides durable, long-lasting fixation without requiring periodic replacement of aging rubber components.
2Strength
If a conventional clamping assembly is used to fix the solar panel, then the solar panel can be installed, but the assembly has poor resistance against air pressure and snow pressure, leading to deformation and dislodgment
Solution Approach 1:
The patent employs an aluminum alloy clamp that combines multiple material properties for enhanced strength. The aluminum alloy provides both structural integrity against atmospheric loads and corrosion resistance, creating a composite-like performance through material selection.
Solution Approach 2:
The clamp features a curved contact surface that conforms to the solar panel frame geometry. This curvature distribution optimizes stress distribution across the contact area, enhancing resistance to air pressure and snow pressure while preventing deformation.
3Ease of operation
If the fixing assembly is disposed on the back of the solar cell assembly, then the solar panel can be fixed, but high installation accuracy is required, especially when the solar panel is near to the ground
Solution Approach 1:
The patent inverts the conventional approach by positioning the clamping assembly on the front side of the solar panel rather than the back. This allows the clamp to engage with the frame from the accessible front side, eliminating the need for high precision backside alignment and enabling easier installation even when the panel is near ground level.
4Force
If a double-glass solar cell assembly is fixed under friction force between the rubber pad and glass surface, then the solar panel can be fixed, but under high pressure the assembly deforms and slides out, increasing moment of force and damaging the clamp assembly
Solution Approach 1:
The patent removes the rubber pad that created the friction-based fixation system. By eliminating the rubber pad, the patent removes the source of deformation and sliding under high pressure, replacing it with a direct structural clamping mechanism that maintains fixation without deformation.
